Revision d07c0278da1f4cfc91c3d46d0d07a0d13a949892 authored by Jaedon Shin on 19 February 2016, 04:48:50 UTC, committed by David S. Miller on 20 February 2016, 04:51:40 UTC
The PHY link state is not chaged in GENETv2 caused by the previous commit 49f7a471e4d1 ("net: bcmgenet: Properly configure PHY to ignore interrupt") was set to PHY_IGNORE_INTERRUPT in bcmgenet_mii_probe(). The internal PHY should use phy_mac_interrupt() when not in use PHY_POLL. The statement for phy_mac_interrupt() has two conditions. The first condition to check GENET_HAS_MDIO_INTR is not related PHY link state, so this patch removes it.
